" bootloader helps to run run arduino code without any external hardware"

o wat it mean external hardware.
It means that you do not need external hardware like a programmer to put code into an arduino.
The job of the bootloader is to take data ( your code ) from the serial port and put it into flash memory ready to run when the processor is reset.
everything okay.generally programmer means, it indicates the human who do the program but you are here indicating its a hardware.could you detial this
The word programmer has two meanings, one is a person who writes programs the other is some hardware that puts code into a chip.
